Abstract
A few studies have been reported that CT cine viewing on the CRT is superio r to him-based viewing of CT images (Seltzer et al., Radiology 197 (1994) 1 19; Bonaldi et al., Am. J. Roentgenol. 170 (1998) 373; Tillich et ai., Am. J. Roentgenol. 169 (1997) 1611). The purpose of our study is to know how to use cine viewing of abdominal CT. Thirty CT studies on the abdomen with bo th precontrast and postcontrast images were examined. The suitable rate of cine viewing ranged from 1 to 6 frames per second according to the size, th e contrast and the complexity of the anatomical structures, and the slice t hickness. For small or complex structures, checking each image might be req uired to know the full detail of them. Positional sorting among multiphase images, which is followed by consecutive display of a precontrast image, po stcontrast early and late phase images at one position and so on, is useful to see the dynamic pattern of enhancement of the anatomical structures. Ho wever, there was no significant difference between cine viewing and film-ba sed viewing concerning both the detectability of the anatomical structures and the conspicuity of enhancement of the liver and the pancreas, so that c ine viewing might be an alternative to film-based viewing for CT diagnosis of the abdomen.
